Application filed. July 9, 1913. Serial No. 778,024,

To all whom it may concern:

Be it known that I, EDWIN ADAM, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Envelope, of which the following is a specification.

This invention relates more especially to 'means or devices for opening an envelop,

- in which like numeralsof reference indicate the usual front 2 and the same parts throughout the several views, Figure 1 is a front view of an envelop embodying my invention; Fi 2 is a perspective view from the back 0 an envelop with the fiap'open; Fig. 3 is a front view similar to Fig. 1, showing the envelop being ripped open, and Fig. 4 is a view similar to Fig. 1, showing a slight rearrangement of parts.

. In the specific embodiment of the invention illustrated in said drawings, the refer ence numeral 1 indicates an envelop havlng back 3, a flap 4: at the top edge of the front being adapted to be bent over and sealed onto the back 3 as is customary and well-known in the art. It is to be understood that the front and back of the envelop unite at their end edges 5,- 5"and with the closed bottom 6 form the usual envelop. Adjacent the top of the envelop these end edges 5, 5 are slit a distance down as at 7, 7 along the crease, as shown in Figs.

1, 2 and a Within the envelop is provided an opener 8 preferably comprlsing a sheet of light weight board, aluminum, or any other substance adapted to the purpose. Said opener 8 is preferably of a truncated triangular formation of a height substantially equal to the height of the envelop and of a width between the two base angles or corners somewhat greater than the length of the envelop. The opener maybe inserted in the envelop Furthermore, by my the truncated triangular opener 8 arrange with the truncated short parallel edge 9 toward the bottom and the long opposite edge 10 extending along the top of the envelop within the same. As the opener 8 is of greater width, however,'than the envelop is long, the corners of the opener will project beyond the end edges5, 5 through the slits 7, 7 as shown, and thereby provide tabs 11,11.

Obviously the receiver of the envelop may open the same by grasping one of the tabs 11 with one hand and holding the opposite lower corner ofv the envelop with the other hand and then pulling apart. In so doing, the sloping edge of the opener 8 extending inwardly downward of the envelop from the tab 11, will rip through the end edge crease 5 of the envelop and open the same forr the withdrawal of the contents of the envelop. The opener furthermore pulls out substantially straight and rips the edge from top to bottom because of the truncated formation which provides substantially parallel opposite edges 9, 10 to engageand be guided by the top and bottom folds of the envelop. improved envelop opener it is unnecessary to fumble the letter around and turn it some particular way so as to grasp it right for opening the envelop since I provide opposite tabs 11 either one of which may be grasped at the convenience of the receiver. I also provide for greater case of inserting the contents into the envelop before sealing the same, by having the long smooth edge of the opener 8 arranged at the top of the envelop, as shown in Figs. 1, 2 and 3. The intended contents may then be easily inserted into the envelop between the front of the same and the opener, the annoyance of the contents catching on the edges of the end flaps in the back of the envelop being thus eliminated.

Obviously it is not essential that the cutting edges be straight, but they might be curved, so long as they are continuous from top to bottom of the opener. noted that the longer edge of the opener, which extends longitudinally of the envelop, is straight to guide the opener and continuous between its intersections with the cutting edges, so that the tabs 11,11 are formed at the intersections of said longer edge with the cutting edges.

In Fig. 4 is shown an envelop 12 having with itslong edge at the bottom ofthe envelop and the corners or tabs 11, 11 pro- Itwill be,

same construction as that first described and it is intended that all such obvious changes are included in the following claims.

It will be noted thatin whichever direction my improved opener is pulled in order to open the envelop a clear space is provided at the rear of the opener for grasping the envelop without holding the opener so as to prevent it from sliding. This is due to the triangular shape of the opener, by which its lower cutaway corners provide finger holds and furthermore since such cutaway corners are at both ends of the opener the envelop can be readily grasped at either end to. draw the opener out at the other end. Great con-- venience and speed in opening the envelop re thus secured.

Having thus described the I claim is.

1. The combination with an envelop having an opening in one end edge adjacent the flap, of an opener comprisin a, sheet having a straight edge adjacent t e envelop flap longer than the envelop and opposite end edges one of which forms with said straight edge a tab adapted to project through the invention, what envelop.

opening in the end of the envelop, the width 0 the body portion of the opener being substantially equal to the width of the envelop, whereby the said straight edge of the opener extends the entire length of the base of the flap and forms therewith a slit to receive a letter or the like and guide the same into the envelop.

2. The combination with an envelop having opposite openings in its end edges adjacent the flap, of an opener comprising a sheet having a straight edge adjacent the envelop flap and two converging edges intersecting said first-mentioned edge at acute angles a distance apart on said edge greater than the length of the envelop, said edge and the cutting edges forming tabs proiecting through said openings in the envelop and the width of the opener being substantially equal to the Width of the envelop," whereby said opener is held by said tabs with its said straight edge of the opener extending the entire length of the base of the flap and forming therewith a slit to receivea letter or the like and guide the same into the EDWIN ADAM.
